For inventors and growing hardware companies
A working prototype isn't a product you can ship by the thousand. We build your pilot run here in the USA, turn it into a production package you own, then place volume with the right factory in the US, Mexico or Asia and stay on top of every batch.
The short answer
Lock the design for production, build a small pilot run, then hand a complete production package to the factory that fits your volume and price. For a first electronic product, expect several months from a working prototype to sellable units, because tooling, testing and certification all sit on the path. We run every step and tell you up front which factory route fits your numbers.
Where are you now?
The stages
Stage 01 of 05
What’s built
A handful of units to prove it works.
What has to pass
The product does its job on the bench.
Stage 02 of 05
What’s built
Tens of units on production-intent boards.
What has to pass
Every electrical and firmware feature works.
Stage 03 of 05
What’s built
Hundreds of units from production tooling.
What has to pass
It passes drop, heat, life and certification tests.
Stage 04 of 05
What’s built
A sellable batch built on the production line.
What has to pass
The line hits its yield and its test plan.
Stage 05 of 05
What’s built
Your full order, batch after batch.
What has to pass
Every batch matches the approved golden sample.
EVT, DVT and PVT stand for engineering, design and production validation tests. Unit counts here are typical for a first product; large brands build far more at each stage.
Pilot runs
Your first sellable units are built by our team, on our line. Everything we make to build them becomes your transfer pack, so the factory starts from a proven process instead of a guess.
The jigs that check every board and every finished unit.
Loads firmware and a unique serial number into every device.
Photo steps for each station, so any factory builds it the same way.
Signed reference units every future batch is checked against.
The transfer pack is yours, in writing. If you ever move factories, it moves with you.
Tooling
For the first handful of units, while the design still changes.
For tens of units that look and feel like molded parts.
For hundreds to thousands, with cheaper changes if you need them.
For tens of thousands and up, built to last millions of shots.
We sign off the design with the factory before any steel is cut, because a change in CAD is cheap and a change in steel isn't. Molds and tooling are registered in your name.
Where to build
The cheapest factory quote is rarely the cheapest product on your shelf. Landed cost adds freight, duties, customs fees and the time your cash is tied up.
Fastest changes, closest oversight, highest labor cost. Best for early runs.
Close by, and goods that qualify under USMCA can enter the US duty-free.
Deep supply chains and low labor cost, with US duties to plan for.
As of November 2026, products made in China usually carry several stacked US duties. Goods made in Vietnam carry a smaller one, and goods from Mexico that qualify under USMCA can enter duty-free. These rules have changed several times since 2025 and parts are being challenged in court, so we confirm the exact rate for your product's tariff code with a licensed customs broker before you commit to a factory.

Quality
We inspect the first units off every new line before the run continues.
Every batch is sampled to a written plan, agreed before production.
No part changes without your sign-off, so certifications stay valid.
Already shipping
We review your parts list, assembly and packaging for real savings.
Approved backup parts, so one shortage doesn't stop your line.
We transfer the process with your pack, then re-check the first batches.
Moving production takes months, not weeks, and quality has to be proven again at the new factory. We plan the overlap so you don't run out of stock.
Cost
Your readiness review gives you a first cost-per-unit range for your product.
Still prototyping? Prototyping. Designing the housing? Product design. Boards and test points: PCB design. Factory programming: Embedded firmware. Before you ship: Certification.
FAQ
It depends on the factory and the process. Our pilot runs in the USA let you build a small first batch without a large factory minimum, then move to a contract manufacturer once your volume justifies it.
You do. Molds, fixtures and the production files are registered in your name, in writing, so you can move them to another factory at any time.
For a first electronic product, usually several months. Tooling, the EVT, DVT and PVT builds and certification all sit on the path. Your readiness review gives you a dated plan.
Labor is cheapest in Asia and Mexico, but landed cost decides. As of November 2026, China-made goods usually carry several stacked US duties, while Mexican goods that qualify under USMCA can enter duty-free. We compare landed cost for your product before you choose.
Yes. We document your current process, build a transfer pack, and check the first batches at the new factory against your golden sample.
Yes. Our programming station loads firmware and a unique serial number into every unit, and it moves to your factory with the transfer pack.
Engineering, design and production validation tests: three build stages between a prototype and mass production. Each one has to pass before the next begins.
A signed reference unit that every production batch is checked against, so quality stays the same from the first batch to the hundredth.
The full cost of a unit on your shelf: the factory price plus freight, duties, customs fees and handling. It's the number to compare factories on.
Assembling the finished product: boards, enclosure, cables, battery, packaging and the final test, ready to ship.
An EMS company assembles your electronics to your design. An ODM sells you its own design with your brand. As the OEM, you own the design; we help you work with the right partner.
Overseas factories often ask for a deposit up front and the balance before shipping.
